To prove how fast such a typo happens, take my e-mail as example. The
spamtrap domain in question is actually "bluwein.ch" and not "bluewein.ch".

Datawire is off the hooks. Turning around the wheel and going North,
towards the lands of Hetzner.

Thanks for all the responses and ideas!

So the research and  journey has begun with Datawire. May it hopefully end
in success. I shall inform you all again, whether or not I've become wiser.

Hi Claudio

For me it looks like, that the domain ‘bluewein.ch’ is not in control of 
Swisscom, but it is in control of the person who most likely also controls 
‘ict-olten.ch’ and ‘cuida.ch’.
You could try to contact Datawire AG, as the IP address of the ‘mailserver’ 
‘mail.ict-olten.ch’ is hosted by them… maybe prepare a message and ask them 
friendly to forward it to their customer. That would be my approach.

Anyway, keep us posted if you find out anything else!

Betreff: [swinog] bluewein.ch - automatic spamtrap?

Hello list,

We are seeing some "mean" behaviour when sending an e-mail to any e-mail 
address ending in @bluewein.ch. Note the difference between 
bluewin and bluewein...

As soon as an e-mail is sent from our relay to this domain, we get listed on 
the UCEProtect-Level1 blocklist. Yes, we can discuss whether or not this is a 
serious blacklist, but some mail providers actually use this service and then 
block our legit e-mails.

Now to this domain. On HTTP all seems in order, the domain is redirected to 
bluewin.ch. But SMTP points to a separate mail server: 
mail.ict-olten.ch. Behind 
ict-olten.ch seems to be nobody (no website, no other 
results so far after a bit of research).

Does anyone here in the list have information about the behaviour of this 
domain and who is responsible for it? Obviously a typo "bluewein" instead of 
"bluewin" happens pretty fast when users are registering and it's already the 
second or third time within a month that we get blacklisted due to a typo from 
users.

thanks for any hints and cheers,
ck

[swinog] bluewein.ch - automatic spamtrap?

[Claudio Kuenzler via swinog]

Hello list,

We are seeing some "mean" behaviour when sending an e-mail to any e-mail
address ending in @bluewein.ch. Note the difference between bluewin and
bluewein...

As soon as an e-mail is sent from our relay to this domain, we get listed
on the UCEProtect-Level1 blocklist. Yes, we can discuss whether or not this
is a serious blacklist, but some mail providers actually use this service
and then block our legit e-mails.

Now to this domain. On HTTP all seems in order, the domain is redirected to
bluewin.ch. But SMTP points to a separate mail server: mail.ict-olten.ch.
Behind ict-olten.ch seems to be nobody (no website, no other results so far
after a bit of research).

Does anyone here in the list have information about the behaviour of this
domain and who is responsible for it? Obviously a typo "bluewein" instead
of "bluewin" happens pretty fast when users are registering and it's
already the second or third time within a month that we get blacklisted due
to a typo from users.

thanks for any hints and cheers,

[swinog] Request for help: academic study (questionnaire)

[Etienne-Victor Depasquale]

***Apologies for cross-posting***

Hello SWINOGers,

I am an academic from the University of Malta


I'm asking for your help through your response to a questionnaire that
forms part of an academic study that I'm carrying out
.

The study is directed solely towards facilitating understanding of metro
area networks, for analysts who approach from the perspective of energy
consumption.

The study is anonymous (no individual or company names are solicited), and
individual responses will only be used in aggregate.

I shall send a digest of the survey to the mailing list, and will
correspond with respondents who would like a copy of the paper which I
intend to produce with the results.


Yours sincerely,

Etienne
